note 85950 added to function.fread

HELLO CODERS. I'm newbie to php and would like to show you a script that do: *Download files from server.(implemanted) *Support resume function.(implemanted) *Determine the speed of download.(implemanted) *Link protection(not yet and that's what I want to learn from you if you like.) I explain the last feature:the server generates a link only "valid for this ip who requested it .the link looks alike something : http://host/downloadit.o-n.php?idx=f7b1424c46ed6705879b2497c6453aaa &file=yogui-cours-complet-php.zip the server support resume,so multiple ranges requests,the same ip could download one more time with this link.Now we need to prevent this from happening using something like this : if($range["start"]!=$dbtikt["down_range"]){//IF4446 //IF THE CLIENT DIDN'T REQUESTED THE CORRECT RANGE. exit(); //WE REFUSE THIS RANGE. }//IF4446 now some tips ii learned: =>to allow download of big files you must add code set_time_limit(0); =>you must proccess the connection abort using ignore_user_abort(true),this means your script will continue executing when the user disconnects from server. so you could use if(connection_aborted()){do something} to perform finshing tasks. =>don't put any thing before <?php code ?>,to avoid header already sent errors,or simply turn on output buffer to prevent php from sending any output until you call flush functions. =>to provide a limiting speed mechanism,i read always 32*speed bytes from file ,flush it and wait a partical time using usleep(round((1000000*32)/1024)) and its working. ---- Server IP: 69.147.83.197 Probable Submitter: 41.251.117.221 ---- Manual Page -- http://www.php.net/manual/en/function.fread.php Edit -- https://master.php.net/note/edit/85950 Del: integrated -- https://master.php.net/note/delete/85950/integrated Del: useless -- https://master.php.net/note/delete/85950/useless Del: bad code -- https://master.php.net/note/delete/85950/bad+code Del: spam -- https://master.php.net/note/delete/85950/spam Del: non-english -- https://master.php.net/note/delete/85950/non-english Del: in docs -- https://master.php.net/note/delete/85950/in+docs Del: other reasons-- https://master.php.net/note/delete/85950 Reject -- https://master.php.net/note/reject/85950 Search -- https://master.php.net/manage/user-notes.php
